SASK-WINDOW.

n e. Jun t may concern:

' lie. it known that I, CARL Fisci-niiua subject of the German Emperor, and resident of Koblenz, Germany, have invented certain new and useful Improvements inb'ash-lvindows, whereof the following is a specification.

My invention relates to a sash-window with two sashes, of which the second or lower can be pushed upward in front of the first or upper sash. Furthermore, the arrangenient is such that the lower or second sash can be shifted up and down in the frame of the window; and, in its lower position, said second sash can be turned on its lower edgeso as to assume a horizontal position.

In the accompanying drawing forining a part of, this specification a constructional form of the inveution's object represented;

Figure l is a front view with onehalfof the window-frame in section, thetwosashes being left away for the sake of greater clearness, Fig. 2 is a vertical section ofthe window with opened sashes, Fig. 3 is a front view, Fig. 4 a side view of the guidin and stopping-device of the lower sash, and Fig. 5 a cross-section of a broken off part of the window-frame.

Similar "letters refer to corresponding parts throughout the several views.

Referring to the drawings, the sashes a and 1: (Fig.2) are guided in the window frame The upper sash n, which is pivoted to the transverse ledger of said windo\\'-fi'aine'r'. so that said sash a can be turned on its lower edge. is opened and closed by means of a device of any desired kind, for example a pulling device coiisisting in a known maunerot acordd led over a system of small rollers or guide-pulleys 1i, and over a roller or pulley d" (Figs. 1 and 2), the latter on being turned by the cord 0'- acting so as to open more or less the upper window-sash (,I l) means of a system of links 0 connected to the top of the frame (2 of said upper sash :1. Further, in each stile of the window-frame c is provided a hollow space or recess f and also a suitably formed longitudinal guide-slot 1 communieating with a further hollow space or recess I: in said window-frame c. In the spaces f slide the counter-weights 1' for the sash I). Said weights 1' are suspended to cords l.- passing over pulleys l and are fastenedwith their other ends to the sash 7). Besides, to

' pivoted a roller 0. Further, each strip m is provided above with a lateral pin "on' which pivots the lower part'of a barorever which is pivoted a rollers. Owing to this in the respective spaces or recesses]: of the window-frame c; Furthermore, on the inof. or is in line with, the nide-slot g (Fig. 2). Into the grooves n of said plates 1 engage the pins n of the strips '11:, when the lowersash b is at the bottom. On said ins n the sash I) 'can be turned as shown inig. 2. In this horizontal position of'the'sashb the pins n are secured or'retained-by pawls pawls r are standing under the action of springsw (Fig. 4), so that on the sash b being turned in its horizontal positib'n, they place themselves with their recessed lower part automatically over the pins '1 as shown in dotted lines in Fig. 4. r

When the sash]; is turned out of the horizontal position into the inclined position pawls -v are pushedaway by the pins a: fixed laterally to the strips 112-, so that the pawls v assume now the position shown in Fig. 4 in full lines. Now, the sash b' can be moved upward vertically in the windowframe. The pins 3 on the plates t limit the position of said pawls v.

If the upper sash is closed, the lower one can be pushed straight upward. Again, if the upper sash a is open, the sash b can be moved out of the window-frame into the po sition if indicated in Fig. 2 by dotted lines.

Having thus fully described my invention, whatl claim anddesi re to secure by United States Letters Patent is with a. window-frame having two lateral guide-ways and provided in the middle-with a transverse ledge, of an upper sash pivoted to the transverse ledge of said windowframe. a lower counterweightedsash, rollers 0 disposed on both sides of said lower sash,

of said lateral guide-ways of the window- Patented Fu'h, 1911.1

-each side of said sash b is screwed a strip";

carrying below a lateral pin'a, upon which I q carrying at its upper end a pin'r upon arrangement the rollers o and s of the two. symmetrical leversystems' in. I, can"slide' side of each stile of the window-frameis arranged, at the bottom of said stile, a'plate t provided with aslot n which forms the end 1' pivoted to the stile of. the window-frame and recessed at their lower part.,-" Said.-

represented in dotted lines in Fig. 2 the 1. In a sashwindow, the combinatio each roller 0 being in engagement. with one frame, two levers q pivoted with their ends to the corresponding sides of said lower sash, and rollers s disposed at the other ends of said levers g, each roller s being inengagement with one of said lateral guideways,.whereby the lower sash is adapted to be brought either in a horizontal position or in an inclined position or even in front of the upper sash by correspondingly moving said lower sash and displacing its rollers in said 'ide-ways; substantially as described.

2. n a sash-window, the combination with a window-frame having two lateral -guide-ways and provided in the middle with a transverse ledge, of an upper sash pivoted to the transverse ledge of said windowframe, a lower counterweighted sash, two strips m fixed to the sides of said lower sash, horizontal pins n connected to the bottom of said strips m, rollers 0 pivoted upon said pins n, each of said rollers 0 being in engagement with one of said lateral guide-ways of the windowframe, two levers q pivoted with their ends to the corresponding sides of said lower sash, horizontalpins r connected to the upper part' of said levers i, rollers s pivoted upon said pins r, each rol er 8 being in engagement with one of said lateralguide-ways, so that the lower sash can be brought -1nto the desired position by cone. spon ingly moving the same and displacing its rollers in said ide-ways of the window frame, substantia d as described. l

strips m fixed to the sides of said lower sash,

horizontal pins n connected to the bottom of said strips m, rollers o pivoted upon said pins a, each of said rollers 0 being in engagement with one of said lateral guideways, plates t fixed to the lower part and in side of the stiles of the window-frame,- each plate t being provided with a groove 11 in one line with the guide-slotg of the window-frame and adapted to receive the corresponding pin a carrying a roller 0, springpressed pawls 'v linked to the lower part and inside of the stiles of the window-frame, each awl '0 being provided below'with a recessed part adapted to lock the corresponding roller pin n, and pins 2: fixed laterally to the strips m, the pawls '0 being pushed aside by said pins :2}, when the lower'sash is turned fromthe horizontal into an inclined position substantially as described.

In witness whereof I have hereunto signed my name this 1 day of May 1909, in the presence of two subscribin witnesses.
